Command to Depart Babylon in Purity

Isaiah 52:11-12

Depart, depart, go out from there, touch no unclean thing! Go out of the midst of her! Cleanse yourselves, you who bear the vessels of the LORD.

For you shall not go out in haste, neither shall you go by flight: for the LORD will go before you; and the God of Israel will be your rear guard.
